Objective

To set up Octopress in its own, isolated Ruby environment

Prerequisite

Install rbenv to manage Ruby virtual environments.

Create isolated environment:

1
2
3

$ export GEM_HOME=$HOME/octopress.gems
$ gem install bundler
$ export PATH=$GEM_HOME/bin:$PATH

GEM_HOME and PATH need to be set to do any Octopress work.

Clone Octopress:

1
2

$ git clone git://github.com/imathis/octopress.git octopress
$ cd octopress 

Install dependencies and default theme:

1
2

$ bundle install
$ rake install

If --path is passed to bundle install, the value is cached in .bundle/config, and $GEM_HOME is subsequently ignored.

Emoji support

• Plugin: https://github.com/chriskempson/jekyll-emoji It is actually necessary to add gemoji to the Gemfile
• Images: https://github.com/arvida/emoji-cheat-sheet.com
• `ln -s …/emoji-cheat-sheet.com/public/graphics/emogis source/images/

The testing ISO image works on a USB key.

Using the nvidia (non-free) driver

To install the nVidia driver:

• make sure installed kernel headers (linux-headers) match kernel (linux-image), otherwise DKMS won’t build.
• install nvidia-driver (note: this will build a kernel module, so requires a working compiler)
• run nvidia-xconfig --query-gpu-info by hand and make note of PCI BusID
• run nvidia-xconfig --busid=PCI:x:x:x to generate xorg.conf

BIOS setup

• Video -> Switchable graphics -> uncheck Enable Switchable Graphics

GNOME 3
